BACKGROUND

The present invention relates to health care, and more specifically, this invention relates to recommending personalized health care based on patient demographics.

Health care is a vitally important aspect of the modern economy and requires using a complex set of information to accurately diagnose patients and recommend appropriate treatment. With the advance of electronic health care records, data-driven health care is an increasing area of interest to health care professionals, and may improve the quality and efficiency with which health care services are provided and patient treatment is accomplished.

In addition, the rising popularity of portable sensors and devices to monitor health conditions provides additional opportunities to observe health status progression with precise metrics. However, currently existing sensors and devices do not provide the ability to monitor all relevant health metrics, and the use of such sensors and devices does not occur to all health care professionals, ultimately leaving a gap between the information needed to improve health care and the ability to collect such information.

Accordingly, it would be advantageous to provide systems and techniques configured to facilitate patient treatment and health care monitoring with a data-driven approach using portable sensors and devices.

DETAILED DESCRIPTION

The following description discloses several preferred embodiments of systems, methods and computer program products for adjusting aspects of a moving platform. Various embodiments provide a method to provide personalized health care to patients based on demographics.

The following description is made for the purpose of illustrating the general principles of the present invention and is not meant to limit the inventive concepts claimed herein. Further, particular features described herein can be used in combination with other described features in each of the various possible combinations and permutations.

Unless otherwise specifically defined herein, all terms are to be given their broadest possible interpretation including meanings implied from the specification as well as meanings understood by those skilled in the art and/or as defined in dictionaries, treatises, etc.

It must also be noted that, as used in the specification and the appended claims, the singular forms “a,” “an” and “the” include plural referents unless otherwise specified. It will be further understood that the terms “includes” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

The term “independently” as recited herein and applied to members of a group, e.g. one or more labels each independently corresponding to a known cause of a particular health condition, is to be understood as meaning each member of the group individually satisfies the stated condition. In the context of the foregoing example, each label corresponds to a known cause of a particular health condition, but different labels may correspond to different health conditions, or the same health condition, in any possible combination or permutation that would be appreciated by a person having ordinary skill in the art upon reading the present disclosures.

The following description discloses several preferred embodiments of systems, methods and computer program products for providing personalized health care to patients based on demographics. More particularly, techniques for predicting likely health conditions for a patient based on demographics, as well as recommending suitable wearable technology to observe occurrence and/or progression of or toward particular health conditions are proposed.

In providing personalized health care to a particular patient population, it is advantageous to predict the major causes of health issues associated with particular patients based on a large demography dataset and personal health history. Given the historical data about demography and personal health, the presently disclosed inventive concepts involve identifying relationships between different demographic attributes and personal health history; predicting the major causes of health issues (e.g. risk factors) associated with health conditions likely to be experienced by the particular patient based on their demographics; and recommend personalized health care accordingly. The personalized health care may include treatment, preventative medicine, and/or observation of biological characteristics (e.g. pulse, blood pressure, cholesterol levels, breathing rate and/or volume, concentration of particular compounds in particular locations or media within the body such as specific oxygen in blood, gene expression levels in particular cell types or organs, etc. as would be understood by a person having ordinary skill in the art of diagnostic and/or predictive medicine, according to various embodiments) using suitable wearable technology.

Accordingly, the presently disclosed inventive concepts represent a technological improvement to the field of diagnostic and/or preventative medicine, in that likely health conditions that a particular patient may exhibit can be predicted with confidence based on demographics of the patient and a large volume of historical health data organized according to demographics. Furthermore, upon identifying likely health conditions for a particular patient, potential causes, risk factors, etc. corresponding to the likely health conditions may be determined, e.g. based on textual analysis of a vast volume of medical and/or academic publications and/or medical data, and appropriate monitoring, treatment, etc. may be recommended in a personalized manner to provide the best quality of care to the patient.

Notably, conventional diagnostic and preventative medicine techniques are incapable of providing the level of confidence in predicting likely health conditions and recommending appropriate monitoring or treatment, because it is practically impossible for health practitioners to parse the vast amount of data represented in the publications and/or medical data. Accordingly, physicians, nurses, and other health care professionals are not capable of reviewing all the pertinent information for each possible combination of demographics that may provide a useful prediction as to likely health conditions and appropriate monitoring for the patient. As a result, health care professionals typically limit diagnoses, prognoses, etc. based on the health care records for the individual patient, coupled with the professional's personal knowledge and experience. The presently disclosed inventive concepts represent an improvement over this conventional paradigm by expanding the data considered in predicting health conditions beyond a patient's individual records and a professional's personal knowledge and experience to include data corresponding to a large number of patients sharing the same set of demographics as the patient for which the health condition is to be predicted.

Moreover, with particular respect to monitoring, medical and academic literature relating to particular health conditions does not typically include information regarding appropriate wearable technology that may be utilized to monitor progression or occurrence of a likely health condition. As such, health care professionals, even if capable of reviewing the vast body of literature and data to determine appropriate likely health conditions based on demographics, would not be privy to corresponding information regarding wearable technology. Thus, providing a robust system and techniques for integrating information regarding wearable technology with medical information such as present in publications and medical databases represents a further technological improvement to the field of preventative and diagnostic medicine.

Health care services is a vitally important industry, and only becomes more so in light of the baby-boomer generation approaching the age range associated with many common diseases such as coronary heart disease, cancer, and various degenerative diseases. The drastic increase in the patient population associated with this transition will put great stress on the already-struggling industry. Health care professionals will need to improve the efficiency with which they can provide quality care to their growing body of patients, lest quality of care suffer due to the added strain. The presently disclosed inventive concepts facilitate improving quality of care by enabling health care professionals to leverage vast quantities of historical medical and demographic information in conjunction with information about wearable technology in order to predict likely health conditions based on patient demographics, as well as integrate these predictions with appropriate monitoring via wearable technology.

Thus, in various embodiments of the presently disclosed inventive concepts, the prediction of likely health conditions for a particular patient are based at least in part on relationships identified between different demographics attributes and associated health conditions, e.g. from a historical dataset; and the patient's personal health history.

In one general embodiment, a computer program product for determining likely health conditions based on demographic information includes a computer readable storage medium having program instructions embodied therewith, where the computer readable storage medium is not a transitory signal per se. The program instructions are executable by a processor to cause the processor to perform a method including: receiving historical demographic data comprising a plurality of attributes; associating the historical demographic data with one or more labels each independently corresponding to a known cause of a particular health condition; building a decision tree model based at least in part on the historical demographic data and the one or more labels associated therewith; generating, based on the decision tree model, a vector Y_(k) representing one or more most probable causes of one or more of a plurality of health conditions; and determining one or more most likely health conditions for a patient based on comparing the vector Y_(k) to a second vector Z_(k), the second vector representing one or more most probable causes of one or more of the plurality of health conditions determined based on a health care record for the patient.

In accordance with another general embodiment, a computer program product for determining appropriate wearable technology and services to monitor a patient for a likely health condition includes a computer readable storage medium having program instructions embodied therewith, where the computer readable storage medium is not a transitory signal per se. The program instructions are executable by a processor to cause the processor to perform a method including: receiving textual data from one or more medical journals and one or more patient health records; identifying one or more concepts by applying one or more query rules to the textual data; generating an entity relationship graph based on the concepts; searching the entity relationship graph to determine one or more measurements associated with one or more most probable health conditions; and determining one or more wearable technologies associated with the one or more measurements.

In yet another general embodiment, a method for determining likely health conditions based on demographic information includes: receiving historical demographic data comprising a plurality of attributes; associating the historical demographic data with one or more labels each independently corresponding to a known cause of a particular health condition; building a decision tree model based at least in part on the historical demographic data and the one or more labels associated therewith; generating, based on the decision tree model, a vector Y_(k) representing one or more most probable causes of one or more of a plurality of health conditions; and determining one or more most likely health conditions for a patient based on comparing the vector Y_(k) to a second vector Z_(k), the second vector representing one or more most probable causes of one or more of the plurality of health conditions determined based on a health care record for the patient.

FIG. 1 illustrates an architecture 100, in accordance with one embodiment. As shown in FIG. 1, a plurality of remote networks 102 are provided including a first remote network 104 and a second remote network 106. A gateway 101 may be coupled between the remote networks 102 and a proximate network 108. In the context of the present architecture 100, the networks 104, 106 may each take any form including, but not limited to a LAN, a WAN such as the Internet, public switched telephone network (PSTN), internal telephone network, etc.

In use, the gateway 101 serves as an entrance point from the remote networks 102 to the proximate network 108. As such, the gateway 101 may function as a router, which is capable of directing a given packet of data that arrives at the gateway 101, and a switch, which furnishes the actual path in and out of the gateway 101 for a given packet.

Further included is at least one data server 114 coupled to the proximate network 108, and which is accessible from the remote networks 102 via the gateway 101. It should be noted that the data server(s) 114 may include any type of computing device/groupware. Coupled to each data server 114 is a plurality of user devices 116. User devices 116 may also be connected directly through one of the networks 104, 106, 108. Such user devices 116 may include a desktop computer, lap-top computer, hand-held computer, printer or any other type of logic. It should be noted that a user device 111 may also be directly coupled to any of the networks, in one embodiment.

A peripheral 120 or series of peripherals 120, e.g., facsimile machines, printers, networked and/or local storage units or systems, etc., may be coupled to one or more of the networks 104, 106, 108. It should be noted that databases and/or additional components may be utilized with, or integrated into, any type of network element coupled to the networks 104, 106, 108. In the context of the present description, a network element may refer to any component of a network.

According to some approaches, methods and systems described herein may be implemented with and/or on virtual systems and/or systems which emulate one or more other systems, such as a UNIX system which emulates an IBM z/OS environment, a UNIX system which virtually hosts a MICROSOFT WINDOWS environment, a MICROSOFT WINDOWS system which emulates an IBM z/OS environment, etc. This virtualization and/or emulation may be enhanced through the use of VMWARE software, in some embodiments.

In more approaches, one or more networks 104, 106, 108, may represent a cluster of systems commonly referred to as a “cloud.” In cloud computing, shared resources, such as processing power, peripherals, software, data, servers, etc., are provided to any system in the cloud in an on-demand relationship, thereby allowing access and distribution of services across many computing systems. Cloud computing typically involves an Internet connection between the systems operating in the cloud, but other techniques of connecting the systems may also be used.

FIG. 2 shows a representative hardware environment associated with a user device 116 and/or server 114 of FIG. 1, in accordance with one embodiment. Such figure illustrates a typical hardware configuration of a workstation having a central processing unit 210, such as a microprocessor, and a number of other units interconnected via a system bus 212.

The workstation shown in FIG. 2 includes a Random Access Memory (RAM) 214, Read Only Memory (ROM) 216, an I/O adapter 218 for connecting peripheral devices such as disk storage units 220 to the bus 212, a user interface adapter 222 for connecting a keyboard 224, a mouse 226, a speaker 228, a microphone 232, and/or other user interface devices such as a touch screen and a digital camera (not shown) to the bus 212, communication adapter 234 for connecting the workstation to a communication network 235 (e.g., a data processing network) and a display adapter 236 for connecting the bus 212 to a display device 238.

The workstation may have resident thereon an operating system such as the Microsoft Windows® Operating System (OS), a MAC OS, a UNIX OS, etc. It will be appreciated that a preferred embodiment may also be implemented on platforms and operating systems other than those mentioned. A preferred embodiment may be written using XML, C, and/or C++ language, or other programming languages, along with an object oriented programming methodology. Object oriented programming (OOP), which has become increasingly used to develop complex applications, may be used.

As discussed herein, logic may be implemented as a method on any device and/or system or as a computer program product, according to various embodiments.

Now referring to FIG. 3, a decision tree 300 for modeling and predicting relevant health conditions based on patient demographics is shown according to one embodiment. As shown in FIG. 3, the decision tree 300 includes three levels 302, 304, 306 each corresponding to a particular demographic attribute and a plurality of leaf nodes 308 each corresponding to one or more health conditions historically associated with patients satisfying a particular combination of demographic attributes. The internal nodes of the decision tree 300 each represent a division among possible values for a particular demographic attribute corresponding to the respective layer 302, 304, or 306 of the decision tree 300.

For example, in accordance with the embodiment shown in FIG. 3, layer 302 comprises a root node corresponding to the demographic attribute of “age” and represents a division according to one or more predetermined age groups that may be used to identify or eliminate relevant health conditions corresponding to each age group.

Layer 304, meanwhile, comprises two internal nodes and a leaf node 308 each corresponding to one of the age groups defined by the root node in layer 302. Those having ordinary skill in the art will appreciate that the decision tree 300 therefore need not be symmetric, and leaf nodes 308 may be present at various levels of a decision tree according to various embodiments of the presently disclosed inventive concepts.

According to the embodiment of FIG. 3, the internal nodes for layer 304 each correspond to the demographic attribute of “gender” (which, in the context of the present disclosures, may refer to biological characteristics, e.g. in the case of physical health conditions such as cancer, cardiovascular health conditions, reproductive health conditions, etc.; or identity characteristics, e.g. in the case of mental health conditions such as post-traumatic stress disorder, depression, etc.) and represent a division between the age groups reflected in layer 302 according to gender.

Meanwhile, the leaf node 308 of layer 304 corresponds to known, likely health conditions (Preferably, the known health conditions in the leaf nodes are the most likely K health conditions for a particular demographic or combination of demographics, where K is a predetermined number of health conditions determined relevant to report, e.g. based on the K health conditions corresponding to a predetermined threshold frequency, percentage, etc. of occurrence within the associated demographic, and/or based on a severity of the health condition(s)) to be experienced by members of the corresponding demographic. In one embodiment, K=5.

For instance, in the embodiment represented by FIG. 3, persons of a predetermined age or older (e.g. 75 years of age or more) may have a certain, high likelihood of experiencing one or more health conditions such as coronary heart disease, Alzheimer's disease, Parkinson's disease, etc. regardless of the person's gender, or place of residence. Accordingly, to maximize computational efficiency of providing relevant recommendations for personalized health care, the decision tree 300 may be built so as to predict the corresponding health conditions based on age alone. Of course, other dispositive demographics or demographic attributes may be employed with respect to different health conditions without departing from the scope of the presently disclosed inventive concepts. As referenced herein, demographic attributes should be understood to encompass a broad category within which various demographic groups may be defined, and demographics refer to the actual demographic group(s) to which various individuals may belong within a particular demographic attribute. For example, a demographic attribute of “age” may include demographics of 0-18, 19-29, 30-39, 40-54, 55-64, 65-74, and 75+.

For other health conditions which may be predicted with greater accuracy or certainty based on additional demographic information, the leaf nodes 308 may reside further down the tree. Accordingly, and with respect to the embodiment of FIG. 3, level 306 includes a plurality of internal nodes each corresponding to a demographic attribute of “current location of residence,” and represent a plurality of different possible places where individuals may reside.

The possible places may be defined with any appropriate granularity that would be appreciated by persons having ordinary skill in the art of diagnostic and/or predictive medicine, and preferably are defined with a granularity that provides the greatest medical relevance to predicting health conditions for a particular patient population. For example, for an international patient population the particular places may include different countries, continents, regions (e.g. tropical, temperate, desert, mountain, jungle, island, etc.), while within a particular country the possible places may include different states, provinces, territories, etc., and while for a particular state the possible places may include different cities, municipalities, etc. As shown in FIG. 3, the internal nodes of level 306 reflect different states where an individual may reside within the United States of America.

With continuing reference to decision tree 300 as represented in FIG. 3, the leaf nodes 308 following level 306 represent the K most likely health conditions for patients satisfying the particular combination of age group, gender, and place of residence reflected by the progression from the root node in level 302 to the respective leaf node 308. For instance, according to leaf node 308 male patients aged 55-64 and living in Alabama, California, or Texas may be most likely to experience coronary heart disease and/or lung cancer, and these conditions may be predicted for patients within this demographic. As will be discussed in further detail below regarding method 500, a particularly advantageous aspect of the presently disclosed inventive concepts is to recommend personalized monitoring using appropriate wearable technology to monitor the progression or occurrence of the likely health conditions for the particular patient. This in turn allows earlier detection and treatment of such conditions, improving the duration and quality of life for the patient.

Preferably, the decision tree 300 is built so as to provide the best possible separation of possible health conditions as high in the tree (i.e. as close to the root node) as possible. As such, the root node preferably represents the demographic attribute that is most dispositive with respect to identifying a particular health condition. For example, different decision trees may be employed to determine most likely health conditions associated with different classes of diagnoses.

In one embodiment, a decision tree configured to determine likely health conditions associated with a particular type of disease known to only affect members of a particular demographic may employ as the root node the corresponding demographic attribute, thereby rapidly eliminating the possibility of patients not belonging to the particular demographic being predicted to experience the health condition(s) associated with the disease that only affects members of the particular demographic. In this manner, unnecessary treatments and/or medical procedures may be avoided, saving cost to the medical industry and the patient, as well as avoiding potential risks associated with such treatments and/or procedures.

In more embodiments, the decision tree 300 may include more or less levels, e.g. based on the number of demographic attributes relevant to predicting and modeling various health conditions, such as age bracket, gender, place of current residence, income level, place of birth, type of employment, lifestyle and/or environmental risk factors, ethnicity, etc. as would be understood by a person having ordinary skill in the art of diagnostic and/or predictive medicine.

Generally speaking, invoking the decision tree 300 as an algorithm may be represented according to the expression (x, Y)=(x₁, x₂, x₃, x₄, . . . x_(n), Y), where x₁ to x_(n) represent demographic values for n demographic attributes, and Y is a health condition associated with the particular combination of demographics represented by x₁ to x_(n). Details of the algorithm will be discussed in further detail below regarding FIG. 4, according to one exemplary embodiment.

Now referring to FIG. 4, a flowchart of a method 400 is shown according to one embodiment. The method 400 may be performed in accordance with the present invention in any of the environments depicted in FIGS. 1-3, among others, in various embodiments. Of course, more or less operations than those specifically described in FIG. 4 may be included in method 400, as would be understood by one of skill in the art upon reading the present descriptions.

Each of the steps of the method 400 may be performed by any suitable component of the operating environment. For example, in various embodiments, the method 400 may be partially or entirely performed by one or more servers, computers, or some other device having one or more processors therein. The processor, e.g., processing circuit(s), chip(s), and/or module(s) implemented in hardware and/or software, and preferably having at least one hardware component may be utilized in any device to perform one or more steps of the method 400. Illustrative processors include, but are not limited to, a central processing unit (CPU), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), etc., combinations thereof, or any other suitable computing device known in the art.

As shown in FIG. 4, method 400 includes operation 402, where historical demographic data comprising a plurality of attributes are received. For example, historical demographic data may include any combination of demographic attributes discussed herein, and is preferably associated with causes of health conditions experienced by the individuals represented within the historical demographic data. In preferred embodiments, the historical demographic data may be received in the form of a text string, which may be parsed from literature, publicly available medical databases, private medical databases, health care records, or any other suitable source of historical medical and/or demographic information and optionally formatted according to a desired convention using any suitable techniques that would be appreciated by persons having ordinary skill in the art of textual information parsing and formatting upon reading the present descriptions. In one embodiment world health organization (WHO) data may be the source of the historical medical and/or demographic information

Furthermore, method 400 includes operation 404, in which the historical demographic data are associated with one or more labels each independently corresponding to a known cause of a particular health condition. In various approaches, each demographic value may be associated with a label, and/or combinations of demographic values may be associated with a label. Deciding the particular labels to apply to particular demographic(s) may be based in whole or in part on training a model using a decision tree algorithm (x, Y)=(x₁, x₂, x₃, x₄, . . . x_(n), Y) as described herein with reference to FIG. 3.

In more embodiments, the labels may additionally or alternatively correspond, independently, to risk factors associated with particular health issues, such as environmental, behavioral, genetic, geographic, etc. risk factors including as exemplars such as consumption of particular substances (e.g. tobacco, alcohol, medications, etc.); lifestyle (e.g. active, sedentary, risk-seeking); travel history or planned travel (especially abroad); mutations or genetic expression information; etc. as would be appreciated by a person having ordinary skill in the art upon reading the instant disclosure.

Thus, and as shown in FIG. 4, method 400 involves building a decision tree model based at least in part on the historical demographic data and the one or more labels associated therewith in operation 406. The decision tree model may be constructed top-down (i.e. root to leaf) based on a training dataset D comprising the historical medical and/or demographic information. Moreover, the entropy and/or information gain may be computed for each attribute A, used for partitioning the decision tree at a given level of the tree. As understood herein, the entropy E may be defined as E[D]=−Σ P(c_(j)) log₂ P(c_(j)), while the information gain G may be defined as G(D, A_(i))=E[D]−E_(Ai)[D], and P(c_(j)) is the probability of an element belonging to class c_(j) in the dataset D.

Preferably, the Attribute A, that has the maximum Information Gain G for a given tree level is used to split the current tree, while minimizing the uncertainty to partition the dataset into different classes at that level. For example, and with reference to the exemplary embodiment of FIG. 3, the Attribute Value “Coronary Heart Disease” is the major cause of health issue in patients belonging to the demographic group of individuals age 75 or older. Hence, this attribute (age) has the maximum Information Gain for the Decision Tree branch of Age-Group 75 and above, and may be employed as the demographic attribute represented by the root node of the decision tree.

Additionally, as shown in FIG. 4, method 400 includes operation 408, in which a vector Y_(k) representing one or more most probable causes of one or more of a plurality of health conditions is generated based at least in part on the decision tree model. The model, according to one illustrative approach, yields a vector Y_(k) of causes of health issues or conditions y_(i) and corresponding probabilities p_(i), and takes the following form: Y:(y₁:p₁, y₂:p₂, y₃:p₃, . . . , y_(n):p_(n)). This vector Y_(k) may be sorted based on p_(i) to compute the top-k causes of health issues or conditions. Subsequently, Y_(k) may be provided for comparison to a second vector Z_(k), as discussed further below with respect to operation 410.

In various approaches, building the decision tree model; generating the vector Y_(k); and/or maximizing the information gain G while minimizing the entropy E may be based on a clustering of demographic values and/or attributes, the clustering being generated based on the historical medical and/or demographic information represented in dataset D. The clustering may be performed using any suitable technique that would be appreciated by a person having ordinary skill in the art upon reading these descriptions, without departing from the scope of the inventive concepts presented herein.

In operation 410, one or more most likely health conditions for a patient based on comparing the vector Y_(k) to a second vector Z_(k), where Z_(k) represents one or more most probable causes of one or more of the plurality of health conditions determined based on a health care record for the patient. Similar to Y_(k), the second vector Z_(k) may take the following general form: Z_(k):(z₁:p₁, z₂:p₂, z₃:p₃, . . . , z_(k):z_(k)). Preferably, the comparison of Y_(k) and Z_(k) includes computing either a union, an intersection, or both, of Y_(k) and Z_(k). The union advantageously represents and predicts the top k health conditions that should be accounted for via appropriate treatment, monitoring, etc., while the intersection predicts a health plan with lesser coverage, but which may be more economically viable for the patient.

In particularly advantageous embodiments, the presently disclosed inventive techniques for identifying likely health conditions based on patient demographics may be coupled with techniques for identifying appropriate wearable technology in order to facilitate monitoring of a patient for occurrence of and/or progression toward the likely health conditions. This facilitates early detection and preventative action, by the health care professional and/or by the patient themselves, and therefore provides an improvement to the quality of care and quality of life experienced by the patient.

In one approach, a suitable method 500 for identifying appropriate wearable technology to monitor a patient for a likely health condition is represented in FIG. 5 The method 500 may be performed in accordance with the present invention in any of the environments depicted in FIGS. 1-3, among others, in various embodiments. Of course, more or less operations than those specifically described in FIG. 5 may be included in method 500, as would be understood by one of skill in the art upon reading the present descriptions.

Each of the steps of the method 500 may be performed by any suitable component of the operating environment. For example, in various embodiments, the method 500 may be partially or entirely performed by one or more servers, computers, or some other device having one or more processors therein. The processor, e.g., processing circuit(s), chip(s), and/or module(s) implemented in hardware and/or software, and preferably having at least one hardware component may be utilized in any device to perform one or more steps of the method 500. Illustrative processors include, but are not limited to, a central processing unit (CPU), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), etc., combinations thereof, or any other suitable computing device known in the art.

As shown in FIG. 5, method 500 includes operation 502, where textual data are received, the textual data being from one or more medical journals, publications, databases, etc. and one or more patient health care records. The textual data may be received in any suitable form, but preferably are received in the form of a text string, which may be generated based on parsing available medical information such as noted above regarding FIG. 4 and operation 402.

Textual analytics may be applied to the received textual data, e.g. text analytics for identifying measurements (e.g. of bio-markers, vital statistics, etc.), to extract concepts from the textual data and identify relationships therebetween. For instance, in one embodiment of method 500, one or more concepts are identified in operation 504, by applying one or more query rules to the textual data.

The query rules may identify keywords that establish a causal relationship between different concepts, where the concepts each independently correspond to one or more topics selected from causes, health conditions, symptoms, measurements, and wearable technologies. Thus, in a preferred embodiment, the one or more query rules each independently represent a relationship selected from: a particular cause that corresponds to a particular disease or health condition, a particular symptom that corresponds to the particular disease or health condition, a particular measurement that corresponds to the particular symptom, and a particular wearable technology that corresponds to the particular measurement, e.g. a wearable technology configured to perform the particular measurement such as pulse rate, blood sugar or insulin level, breathing rate and/or volume, neurological activity, etc. as described herein and as would be understood by a person having ordinary skill in the art upon reading the present disclosure.

For example, in one embodiment textual data may indicate: (1) lung diseases are typically caused by smoking (linking a health condition to a cause); and (2) lung disease is exemplified by symptoms including prolonged cough, expectation of sputum, blood in sputum, fatigue, weakness, shortness of breath, and/or chest pain. Textual data may also indicate (3) that a normal respiration rate is in a range from approximately 12-20 breaths per minute, and (4) an existing wearable technology is available and is configured to track a user's physical activity, breathing rate, and state of mind. From this textual data, query rules may be developed establishing relationships between the cause and the health condition (per item 1); the symptoms associated with the health condition (per item 2); the appropriate measurements to monitor the patient for occurrence and/or progression of such symptoms (per item 3); and a suitable wearable device to recommend the patient use for monitoring purposes (per item 4).

Accordingly, in operation 506, method 500 involves generating an entity relationship graph based on the concepts extracted from the textual information. The entity graph may take any suitable form, and preferably includes an aggregation of relationships determined by extracting the concepts from the textual data. For instance, in one embodiment the relationships may be the edges of the graph, while extracted concepts are nodes of the graph.

With continuing reference to method 500 and FIG. 5, in operation 508 the entity relationship graph is searched to determine one or more measurements associated with one or more one or more most probable health conditions for the patient, e.g. based on identifying relationships between measurements and wearable technologies corresponding to the one or more most probable health conditions for the patient. The search may be performed using any suitable technique that would be appreciated by a person having ordinary skill in the art upon reading the present disclosures without departing from the scope of the inventive concepts presented herein.

Upon determining the measurements, one or more wearable technologies associated with the one or more measurements are determined in operation 510 of method 500, according to preferred embodiments.

The determination of wearable technology may include first determining whether any suitable wearable technology exists and is appropriate for the patient's use in monitoring their health status, and if so determining a most appropriate wearable (e.g. a wearable technology which is configured to measure the greatest number of measurements the patient should monitor) to recommend for the patient's use. A recommendation as to the patient's use of the appropriate wearable, and any appropriate services associated therewith (e.g. automated recording and reporting of data, alerts to the patient, etc.) may be rendered to the patient and/or health care professional, in some approaches.

If no appropriate wearable technology is available, the presently disclosed inventive concepts preferably include outputting an indication of such, and recommending the lack of such technology be reported, e.g. to an application or device developer who may then pursue a wearable technology to be implemented in the future and assist patients in monitoring their health status.

In various embodiments, the present invention may be a system, a method, and/or a computer program product. The computer program product may include a computer readable storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out aspects of the present invention.
